本文介绍了一个使用 Hessian 实现的远程过程调用 (RPC) 示例。通过 Java 的 Eclipse Jetty 服务器部署服务端，并创建客户端进行调用验证。服务端提供了一个简单的字符串返回方法，客户端能够成功获取并打印该响应。

Servercode:

import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.servlet.ServletContextHandler;
import org.eclipse.jetty.servlet.ServletHolder;

public class HessianTest {

public static void main(String[] args) throws Exception {
Server server = new Server(8080);
ServletContextHandler context = new ServletContextHandler(
ServletContextHandler.SESSIONS);
server.setHandler(context);
ServletHolder servletHolder = new ServletHolder(new BasicService());
context.addServlet(servletHolder, "/test");
server.start();
server.join();
}

}

Basic interface:

public interface Basic {

public String hello();
}

Basic implementation:

public class BasicService extends HessianServlet implements Basic {

public String hello() {
return "Hello! It works!";
}

}

Client application:

import com.caucho.hessian.client.HessianProxyFactory;

public class HessianClient {

public static void main(String[] args) throws Exception {
HessianProxyFactory factory = new HessianProxyFactory();
Basic basic = (Basic) factory.create(Basic.class,
"http://myhost:8080/test");
System.out.println("Hello: " + basic.hello());

}

}
